The 50 Best Websites of 2011

Instapaper offers nothing to read of its own. It just makes most of the stuff you read on the Web better. Click its "Read Later" button and you can save articles and other reading materials, and then peruse them at your leisure in beautifully reformatted versions that strip out ads and other distractions. Better still, you can do that perusing in your browser or on an iPhone or iPad. (Archival Read It Later is similar and also works on Android phones; its formatting isn't quite as successful, in our experience.)
